Talking of occult philosophy, here's a picture of an autograph penned by Jimmy Page.
93 93/93 is an Aleister Crowley-approved quick way to write, "Do what thou wilt shall be the whole of the law. Love is the law, love under will." Which is a slow way to write "Greetings".
Here's the explanation. I assume the autographee was a casual acquaintance - good friends don't ask for autographs usually. But it's still interesting that Jimmy Page can spell "Greetings" in his fan's native tongue. I think.
I don't know where the picture originally came from, or whether the owner is claiming copyright, so if it's being distributed without their knowledge, perhaps they could drop me a line and I'll remove it.
